An increasingly popular name for the post-apocalyptic world in which the events of the My Chemical Romance 2010 album "Danger Days: The True Lives Of The Fabulous Killjoys" take place. The year is 2019 or thereabouts, and an unknown, but likely nuclear disaster, has turned the world into a place similar to the setting of the Fallout series.
Term never officially used by the band, but coined by a fan in a popular tumblr blog very early in the album's history.

There's been Dangerverse fanfiction ever since the first Danger Days single was released, but it's really ballooned after the full album release.
